9 T estoration of the atrophied edentulous maxilla poses great dilemma to the oral and maxillofacial surgeon nd restorative dentist. Conventional removable denure prostheses are adequate for some individuals; but mproved technology in dental implantology has led any to request alternative approaches with imlants. Patients with adequate maxillary bone are deal candidates for implants, but are th...

In a 12-year period, 56 consecutive patients have undergone secondary periorbital reconstruction after trauma. To evaluate the overall results and the need for further correction, three diagnostic groups were formed. These were: malar bone (n = 16), midface (n = 16) and fronto-orbital fractures (n = 24). Also, in order to judge the reliability of the procedures used most frequently, all osteoto...

Prosthetic rehabilitation of the edentulous posterior maxilla with implant-supported prostheses frequently presents a challenge for the oral surgeon because of the lack of bone due to alveolar ridge resorption or maxillary sinus pneumatization. To overcome these problems, different solutions were proposed over the years, such as the use of short implants or tilted implants (including zygoma imp...

The AOCMF Classification Group developed a hierarchical three-level craniomaxillofacial classification system with increasing level of complexity and details. The highest level 1 system distinguish four major anatomical units including the mandible (code 91), midface (code 92), skull base (code 93), and cranial vault (code 94). This tutorial presents the level 2 system for the midface unit that...

AIM This study was designed to determine the anatomic position of the asterion and the relationship between the asterion and the transverse sigmoid sinus junction (TSSJ) in a Chinese cohort. MATERIAL AND METHODS Venous computed tomography (CT) angiography was performed in 32 patients to simultaneously obtain 3D-CT volume rendering images of the cranial bone and the dural sinus. The relationsh...

STATEMENT OF PROBLEM Oral rehabilitation of the edentulous atrophic maxilla to allow placement of a fixed dental prosthesis remains a challenge, especially if immediate function is provided. PURPOSE The aim of this retrospective, preliminary study was to evaluate, after a period of a 6 to 29 months' follow-up of prosthetic loading, the survival rate of 36 immediately loaded zygomatic implants...

PURPOSE The purpose of this prospective study was to evaluate the safety of zygomatic bone harvesting and to determine whether a particulated zygomatic bone graft can be used simultaneously with 1-stage dental implants to reconstruct resorbed edentulous alveolar ridges. MATERIALS AND METHODS Altogether, 82 dental implants were placed in 32 patients. Particulated bone grafts harvested from the...

BACKGROUND Zygoma is a major buttress of the midfacial skeleton, which is frequently injured because of its prominent location. Zygoma fractures are classified according to Knight and North based on the direction of anatomic displacement and the pattern created by the fracture. In zygomaticomaxillary complex (ZMC) fracture many incisions (lateral eyebrow, lateral upper blepharoplasty, transconj...
